The name Yvetot comes from the Germanic
Yvo and the Old Norse
-topt. Therefore, Yvetot means 'property of Yvo'. The lords of Yvetot bore the title of king from the 15th until the middle of the 16th century, their petty monarchy being popularized in one of
Béranger's songs. In 1592,
Henry IV here defeated the troops of the
Catholic League. The town's prosperity was linked to strong commerce, developed as early as the 17th century, thanks to its fiscal statutes and to
cotton spinning, which saw massive expansion after 1794. In the 19th century, the town developed fabric production. Until 1926, Yvetot had been
chef-lieu of the old
arrondissement of Yvetot, and a sub-prefecture. During this period of reorganisation, it lost its status of sub-prefecture. In
World War II, Yvetot was practically razed in 1940 by the Germans. Later, the 75th Division of the U.S. Army,
575th Signal Co., maintained its command post in the town from December 14–20, 1944, as it counterattacked against the German army. After the war, Yvetot was rebuilt in a classical style and regained its importance in the middle of the 20th century.
